View All Members
Upon clicking "Members" on the Main menu or in the Info Center you will be lead to this page. The "View all Members" page is the default page for the memberlist section. But there is also a Search for members page in the memberlist as well where you can search for members registered on a forum.
On this page you will see the list of all the members registered on the forum you are viewing. At the top you will be able to navigate through the pages of members, which are used so there won't be too many members on one single page. On the right side of the "Members List" title bar, you will see every letter of the English alphabet. Clicking on a letter will lead you to registered members thats username begins with that letter. Note this does not filter out all of the other usernames beginning with different letters, but rather serves as an anchor so you will be directed to usernames that start with the letter clicked so you don't have to scroll through several pages to find usernames that begin with a certain letter.
All usernames in the memberlist can be ordered in several different ways.
They can be ordered by: Status (Online - Offline), Email, Website, ICQ, AIM, YIM, MSN, Position, Date Registered, and Posts. Just clicking on one of these links will sort the members for you. First in descending order, but when clicked again - in ascending order.
Search for members
This section allows you to search for members of your forum using many different filters. You can search for members with an ID, age, posts, date registered, last online; with the values of: less than value inputted, less or equal to, exactly equal to, equal to or greater, or just greater than. So for example, you could use Posts => 300 and User age > 20 to list all members that have 300 or more posts and are older than 20 years of age.
You can narrow the search down even more by selecting the gender of the members you wish to list, the activation status of the member, and the membergroups the member belongs to.
You can also try to find members by their username, email address, website, location, ip address, and messenger address.
